Ebay Site without Auction and ability to download products

I am looking for a script/database to start a website that will sell documents online. The twist is that I want it to be like ebay without the auction aspect. I want users to be able to login and sell documents which they have uploaded onto my server set a price for them and sell them much as people sell physical objects on ebay. Yes, people sell electronic documents online but they email them to the highest bidder after they have won the auction. I want the person to be able to download the document the seller has uploaded. Then of course I want to take a percentage from the sale.

The closest thing I have found is [url removed, login to view] which is just another ebay script/database. I like the price design simplicity, but don't want the auction aspect and need the ability for users to upload files that they will be selling and on the other end I need visitors to be able to immediately download the document after paying.

Please let me know if you could create such a script/database or better yet where I could buy one just like they sell them on [url removed, login to view] .
